Micro-segmentation is the art of using software-defined policies, instead of hardware network configurations, to make network security more flexible. It can only work if implemented with right tools and forethought.
Models used in micro-segmentation
There are four architectural models used in micro segmentation. They are:
Hybrid model – it is a combination of third-party and native controls
Overlay model – usually uses a type of software or agent within every host, instead of using moderating communications. Vendors of this model include Unisys, vArmour, Vmware NSX, Shield
